I am a fan of most varieties of Dogfish Head. Here's another one I have to recommend: their Saison du Buff, a collaboration among Dogfish Head, Victory Brewing Company and Stone Brewing Company. As the label says, it is an "ale brewed with parsley, sage, rosemary & thyme". It leaves a nice, light, crisp and, indeed, herbal flavor. Now if they could only do a basil-flavored beer.
